The structure of the interview was a classic consulting first round interview. The first 40 minutes of the interview were about my personal experiences, professional experiences and carrer aspirations/goals. The last 20 minutes were case questions (2), more specifically "market sizing" questions. Interviewers also asked a few questions about initiatives I took in my community (volunteering...). The interview was formal, but the interviewers were very nice and it took the form of a discussion rather then back-to-back questions. Advice: - Don't be afraid to ask for clarifications in the case questions, especially if you are not familiar with the industry. - State your assumptions clearly during case questions and explain your calculations.
